Cephalexin is a first-generation cephalosporin antibiotic, effective against a range of gram-positive and some gram-negative bacteria. It’s often prescribed for skin infections, respiratory tract infections, urinary tract infections, and bone and joint infections. Always follow your doctor’s instructions regarding dosage and duration of treatment.
Dosage and Administration
Dosage varies depending on the infection’s severity and the patient’s age and weight. Typical adult doses range from 250 mg to 1 gram, administered every 6 to 8 hours. Children’s dosages are calculated based on weight, usually 25 to 50 mg per kilogram of body weight per day, divided into doses. Oral administration is standard, with medication taken with food to minimize stomach upset.
Side Effects
Common side effects include diarrhea, nausea, vomiting, and abdominal pain. Less frequent but potentially serious side effects involve allergic reactions (rash, itching, swelling), pseudomembranous colitis (a severe bowel infection), and changes in blood cell counts. Seek immediate medical attention if you experience any severe allergic reactions or significant side effects.
Drug Interactions
Cephalexin can interact with certain medications, including anticoagulants (blood thinners) and some diuretics (water pills). Inform your doctor about all medications, supplements, and herbal remedies you’re taking to prevent potential interactions. Alcohol consumption during treatment should be minimized, as it can exacerbate potential side effects.
Contraindications and Precautions
Cephalexin should be avoided by individuals with known allergies to cephalosporins or penicillin. Pregnancy and breastfeeding require careful consideration and consultation with your physician. Kidney problems may necessitate dosage adjustments to prevent medication buildup. Patients with a history of gastrointestinal issues should be monitored closely.
Alternatives
If cephalexin is unsuitable, alternative antibiotics may be considered, depending on the specific infection and the patient’s individual circumstances. Your doctor will determine the most appropriate alternative based on your medical history and the bacteria causing the infection.
